Ye' old general discussion board. Basically, for everything that isn't covered elsewhere. Come here to shoot the breeze, shoot your mouth off, or whatever suits your fancy. This forum is not for asking programming related questions.
Back when I had Norton Systemworks I used it's registry cleaner a couple times. My recommendation? If you're not having some specific problem, don't run a registry cleaner just for the heck of it. Typically even if you clean out some orphaned path or object, you won't see any difference in the way your computer runs.
Wasn't for a specific problem as such, just trying to speed up an ancient laptop that's had a great many different bits of software installed and (sometimes unsuccessfully) uninstalled.
